I presume now you will say that all the actions that BG's administration takes are based solely on maximizing page views and ad revenue, just as you do for FFXIwiki's administration, right?
Citing your sources and giving credit is the polite, courteous thing to do.
Failing to do so is not cause for accusing them of stealing others' work and founding an entirely new competing wiki, designed specifically to push them out of relevance.
P.S. Do not take my post as an attack on BG's administration for putting up ads. I am aware that web hosting does not magically pay for itself. I am simply pointing out the absurdity of people who claim that hosting ads on your site means that every decision you make henceforth must be squarely focused on page count and profit margin.
